IMPROVEMENT IN ALLOYS OR BELL-METALS.

Specification forming part of Letters Patent No. 130,814, dated August 27 1872.; antedated August 20, 1 872.

county of Suffolk and State of Massachusetts.

To prepare my compound melt one pound nickel; add six pounds copper; melt and cool; add two pounds zinc and one-half ounce aluminium; melt and cool; add, after melting the above, one-half ounce quicksilver and six pounds melted copper; or cool the above before adding the copper if thought best. In large bells fifty to a hundred per cent. nickel additional may be added, making the nickel one and one-half to two pounds, and in that proportion, instead of one pound, as above mentioned. To make the composition of amore deeply yellow color add apound or so of zinc, or in that proportion. a

My advantages over the common bell-metal are, first, this composition will not tarnish as much as will bell-metal generally, and the tarnish that does appear may be easily removed with a woolen rag without hard rubbing or scouring, as is now necessary; second, my composition, when manufactured into bells, produces a better vibration, and consequently a more satisfactory tone; third, bells made from this compound are less liable to crack with violent ringing, as the material issofter than ordinary bell-metal fourth, a bell made from bells isabout the same; hence my bell can be made cheaper in the same proportion.

The above-described method of mixing the ingredients is the best, probably, but not the only method. It may or may not be rigidly adhered to.

In order to render the compound above described somewhat harder and tougher I may vary it slightly by leaving out the second lot of six pounds copper and by reducing the quantity of zinc to one and one-half ounce, making the composition as follows: six pounds copper, one pound nickel, one-half ounce aluminium, one and one-half pound zinc, onehalf ounce quicksilver. This modification will make it valuable where a tougher metal is needed, and perhaps for some other purposes besides making bells.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The above-described compound, substantially as and for the purposes hereinbet'ore set forth.
